1st Build, Steel, Epoxy 24"x24" for Wood

Can I get opinions on this kit: https://www.ebay.com/itm/FEEE-Ship-3....c100005.m1851

Kits are never a good idea as the are never matched. The motors are too high in inductance, you would be better off with higher voltage drives and power supplies. The machine look bigger than 24"x24". It would be nice if you could rotate the pics.

I'll keep that in mind. I was thinking it might be cheaper - but if it's wrong... I still don't understand why my pics get rotated 90 degrees when uploading. I guess I'll try rotating them 90 the other way *before* I upload.

Thanks,

Given you're on the other side of the pond, I would of thought Gecko drives would be a reasonable first choice, as you won't have the issue of import tax and VAT to worry about, which makes them poor value here.
However Leadshine AM/EM drives might be worth considering for the sole benefit of having stall detection, which I'd recommend for any twin screw axis (should a single screw axis stall, it's not normally a major problem machine wise, but on a twin screw axis, you risk twisting the gantry if one screw stalls and the other keeps going - even with stall detection you'll likely still get some twisting, but all motion should stop far quicker minimising or eliminating damage).

Gecko used to also sell some pretty low inductance Nema23 motors, but I see they've stopped selling them.
I'd have a search of the more American based forums to see where people are sourcing motors.
